Only The Beginning



While the average cossetted North American may feel smug about the following, since the water shortages discussed seem far, far away, they are the stuff that social unrest, rioting, regime change and mass migrations are made of:
Countries that are home to one-fourth of Earth’s population face an increasingly urgent risk: The prospect of running out of water.

From India to Iran to Botswana, 17 countries around the world are currently under extremely high water stress, meaning they are using almost all the water they have, according to new World Resources Institute data published Tuesday.
Greatly exacerbated by climate change, floods and droughts are becoming more volatile:
Water-stressed places are sometimes cursed by two extremes. São Paulo was ravaged by floods a year after its taps nearly ran dry. Chennai suffered fatal floods four years ago, and now its reservoirs are almost empty.
Unfortunately, the short-term solution many countries have adopted, tapping deep into their aquifers, only promises a deferment of the crisis:
Mexico’s capital, Mexico City, is drawing groundwater so fast that the city is literally sinking. Dhaka, Bangladesh, relies so heavily on its groundwater for both its residents and its water-guzzling garment factories that it now draws water from aquifers hundreds of feet deep. Chennai’s thirsty residents, accustomed to relying on groundwater for years, are now finding there’s none left. Across India and Pakistan, farmers are draining aquifers to grow water-intensive crops like cotton and rice.
Are there any solutions? Not really.
...city officials can plug leaks in the water distribution system. Wastewater can be recycled. Rain can be harvested and saved for lean times: lakes and wetlands can be cleaned up and old wells can be restored. And, farmers can switch from water-intensive crops, like rice, and instead grow less-thirsty crops like millet.
Given the world's ever-increasing population, the quickening pace of climate change and humans' reluctance to alter their profligate ways, it is a safe bet that things will get worse. Clearly, this is only the beginning of the horrors that await the planet.
